I'm going to put out a small release to fix a couple of possible crashes. This release will also include some changes to the tool bar on the calculator (where you can quickly switch between factor/simplify, decimal/integer, etc.).
After this release, I am going to go through the tutorials and update the screen shots with the changes. Also, I will update them to include some of the new features that have come out in the past few releases that I haven't added to the tutorials yet.
